I have a recipe I can post later this evening when I get home. It's close to the Urbock, since that's what I was going for, but the real deal is smokier, likely due to the fact, as mentioned above, Schlenkerla smokes all the malt in the recipe, whereas with mine, only the Weyermann Rauchmalt is smoked. If you have the means to smoke all of your malts it will get you closer to the real thing and if you did that, I would suggest you also re-smoke the Rauchmalt (or save some $$$ and smoke your own pils malt). My recipe does make a nice Urbock, though, IMHO.
